Full technical basis and contextOpen this section to read the complete source technical narrative.
The Shallow-Water Spectral Wave Model Module is well suited for simulating wind-generated wave propagation in shallow waters, including wave formation processes and the dissipation of short-period waves, where wave breaking commonly occurs. This module can also represent wave refraction and shoaling caused by changes in water depth, local wind conditions, and wave energy dissipation due to bottom friction and wave breaking. In addition, the module can simulate the interaction between waves and currents.
This wave module is a stationary, directionally decoupled, parametric wave model. The interaction between waves and currents is represented using the conservation equation for wave action density. The parameterization of the conservation equation in the frequency domain is formulated using the zeroth and first moments of wave action as independent variables.
The frequency spectrum is assumed to consist of individual wave peaks. Therefore, complex sea-state interactions, such as interactions between open wind-waves and swell, cannot be simulated directly. The governing equation is solved using a finite Eulerian differentiation technique on a rectangular grid with several discrete wave-direction components.
This module is particularly useful for assessing wave disturbances along coastal areas. A detailed analysis of wave height, wave period, and wave direction is essential for estimating wave-induced forces along the shoreline. In coastal engineering, this information is especially important for sediment transport studies, because nearshore sediment movement is strongly controlled by wave conditions and wave-associated currents. Wave-induced currents are generated by wave radiation stresses acting on the water surface.
